socket_problem

How can I make this server to send any type of file format apart from html?
NOTE:SENDING() FUNCTION
CODE :

Code:

#include<stdio.h>
#include<sys/types.h>
#include<sys/socket.h>
#include<netinet.h>
#include<string.h>
#define port 1234
#define buffer_size 1024
#define CLEARSCREEN "\x1B[2J"
#define MAXCONNECTIONS 3
void sending (int sd,char *f1, char *prt);
struct sockaddr cli,ser;
main(){

int d,t=0,r,q,sd,b,i,j,con=1,id;
char buf[buffer_size+1],*method,*path,*prt;
char line[buffer_size];
struct sockaddr_in cli,ser;
int sw;
printf(CLEARSCREEN);

d=socket(AF_INET,SOCKSTREAM,0);
if(d>0)
	printf(("\n Socket created");
else{
	puts("socket not created");
	exit(0);
}
 ser.sin_family=AF_INET;
 ser,sin_port=htons(port);
 ser.sin_addr.s_addr=INADDR_ANY;
 r=sizeof(struct sockadrr);

 b=bind(d,(struct sockaddr *)&ser,r);
 if(b<0)
 exit(0);
 
 listen(d,MAXCONNECTIONS);

 do{
 q=accept(d,(struct sockaddr *)&cli,&r)
 id=fork()//unix multitasking
 if(id==0)
 printf("The client %S is connected", inet_ntoa(cli.sin_addr);
 sz=sizeof(buf);
 i=read(q,buf,sz);
 buf[i]=0;
 for(i=0;i<buffer_size && buf[i]!='\r'&&buf[i]='\n';i++)
	{
 	line[i]=buf[i];
	}
 line[i]=0;
 
 method=strtok(line," ");
 path=strtok(NULL, " ");
 prt=strtok(NULL," ");

 if(strcmp(method, "GET")!=0)
 exit(0);
 
 sending(q, path, prt);
 con++;
}while (con<=MAXCONNECTIONS);
close(d);
}


void sending(int sd,char *path, char *prt)
{
 char ch, header[buffer_size + 1];
 int len;
 FILE *fp;
 path++;
 fp=fopen(path, "r");
 sprintf(header, "%s 200 ok\r\nContent_type :text\html\r\n\r\n", prt);
 len=strlen(header);
 write(sd,header, len);
 
 if(fp==0)
 fp=fopen(filenotfound.html,"r");
 do{
 ch=fgetc(fp);
 if(ch!=EOF)
 write(sd,&ch,1);
 }while(ch!=EOF)
 
 fclose(fp);
 shutdown(sd,1);

}

Code:

sprintf(header, "%s 200 ok\r\nContent_type :text\html\r\n\r\n", prt);

Does this mean that I woulkd have to edit this line anytime I need to include other file types?
How do I get the server to detect the file being requested automatically?
And thanks for noticing some of those minor errors.
Hope this is better:
